Delayed alternation and object alternation are classic spatial and non-spatial delayed response tasks. We tested 632 middle-aged male veteran twins on variants of these tasks in order to compare test difficulty, measure their inter-correlation, test order effects, and estimate heritabilities (proportion of observed variance due to genetic influences). Non-spatial alternation (NSA), which may involve greater reliance on processing of subgoals, was significantly more difficult than spatial alternation (SA). Despite their similarities, NSA and SA scores were uncorrelated. NSA performance was worse when administered second; there was no SA order effect. NSA scores were modestly heritable (h(2)=.25; 26); SA was not. There was shared genetic variance between NSA scores and general intellectual ability (r(g)=.55; .67), but this also suggests genetic influences specific to NSA. Compared with findings from small, selected control samples, high "failure" rates in this community-based sample raise concerns about interpretation of brain dysfunction in elderly or patient samples. 相似文献

This article describes the development and validation of a scale that measures two distinct needs for individuals to manage their social "face". Scale development process resulted in an 11-item Consciousness of Social Face (CSF) scale made up of the following two correlated dimensions: desire to gain face and fear of losing face. The two-factor correlated structure of CSF scale was stable across multiple samples of both students and non-students subjects. The construct validity of CSF scale, including convergent validity, discriminant validity, and criterion-related validity was also demonstrated by examining relationships with other personality or demographical variables. 相似文献

企业网络的治理机制是保证网络间企业有序运作的前提。和科层组织的治理机制不同,企业网络的治理主要是靠非正式机制,即所谓的网络机制。本文从关系性嵌入、专用性投资以及联合制裁三个方面对此问题进行了阐释。本文的结论是,企业网络中特有的治理机制是导致企业网络竞争优势的一个重要原因。 相似文献

论邓小平稳定周边的战略思想与中国的亚太战略 总被引:2,自引:0,他引:2
党的十一届三中全会以后,邓小平一方面继承了毛泽东,周恩来等党的第一代领导集体的睦邻外交思想,另一方面又根据国际形势与时代主题的变化和我国周边安全环境新特点,提出了稳定周边的战略思想。邓小平稳定周边的战略思想的主要内容是:睦邻友好、争取良好的周边环境是我国现代化建设的迫切需要;中印两国没有根本的利害冲突,双方合作的前景十分广阔;不管苏联怎么变化,我们都要同它从容地发展关系;中日两国要永远友好下去,这是中国的长期国策;以“搁置主权,共同开发”解决领土争端,促进中国与周边邻国的友好合作关系;以“一国两制”解决历史遗留问题,维护地区和平。在邓小平稳定周边的战略思想的指导下,中国积极推行成功的亚太战略,取得了丰硕成果,从而为我国改革开放和社会主义现代化建设创造了良好的周边外部环境。 相似文献

This article reports on an experiment designed to test whether the cartoon manipulation leads to significant increases in aggressive thoughts and aggressive behaviors among Chinese children (n = 3,000). Results indicated that brief exposure to a violent cartoon triggered higher aggressive thoughts and aggressive behaviors than a nonviolent cartoon. Females displayed higher aggressive thoughts and aggressive behaviors than males in a nonviolent cartoon condition, while males displayed higher aggressive behaviors than females in a violent cartoon condition. Mediation analysis suggested that the effect on aggressive behaviors was mediated by aggressive thoughts. The findings imply that cartoon developers, parents, and teachers should develop cartoons that inhibit children's aggressive thoughts to avoid aggressive behaviors. Females are the key group for the prevention and intervention of aggression in a nonviolent cartoon context, while males are the key group for the prevention and intervention of aggression in a violent cartoon context. 相似文献
